A stapler firing force detection device

Abstract

The invention discloses a device for detecting the triggering force of a surgical stapler. The device comprises a support mechanism, a moving component, a data processing module and a control module, wherein the control module comprises a motor and an output module; the support mechanism is used for fixing a to-be-detected surgical stapler; the support mechanism comprises a fixing block which is separated or closed through rotation; after the fixing block is closed, at least one part of the to-be-detected surgical stapler is fixed in the fixing block; the motor drives the moving component to trigger the surgical stapler; the data processing module senses the triggering force provided by the motor, collects and processes the triggering force and outputs a detecting result to the output module. The device has the advantages that the to-be-detected surgical stapler can be mounted or taken out by rotating the fixing block, the triggering force is detected through data collecting and data processing, the detection value is digitally displayed, and whether the triggering force of the surgical stapler satisfies surgical requirements or not can be judged.

Description

technical field [0001] The invention relates to a detection device for surgical instruments, in particular to a detection device for the firing force of a stapler, which belongs to the field of medical instruments. Background technique [0002] The stapler and its executive components suitable for surgical operations are surgical instruments that can remove excess tissue while suturing the patient's wound. It is widely used in minimally invasive surgery such as abdominal surgery, gynecology, pediatrics, and thoracic surgery. Excision and anastomosis. The operation carried out under the endoscope generally only needs to open several small holes on the patient's body, and excision, suturing tissue and auxiliary instruments are inserted into the patient's body through the small holes for surgery. Minimally invasive surgery brings little trauma to patients, and patients can recover in a short period of time. Therefore, minimally invasive surgery has attracted more and more atte...

Problems solved by technology

Due to the internal structural design of the existing stapler, the next effective firing can only be performed when the firing handle and the positioning handle cannot be moved each time. The insufficient firing force applied by the operator will make the firing handle not fully connected with the positioning handle. Abutting thus affecting the normal use of the stapler

In this case, it can only be fired again, and because the patient's tissue is clamped in the end effector of the stapler, firing again will cause accidental injuries such as tearing to the patient, affecting the normal operation

Therefore, it is necessary to detect the firing force of the stapler, and the detection of the firing force of the stapler in the prior art can only rely on the feel of the inspector, there is no effective device for detecting the firing force of the stapler, and there is no objective data support
